摘要：

Novel imidazolylethynyl-zinc-porphyrin 1a and its meso,meso-linked bisporphyrin 5M were synthesized effectively by the reaction of the corresponding bromoporphyrins and 2-imidazolylethyne in the presence of palladium-arsenic catalyst. The complementary coordination of monomer 1a into dimer 2a was observed by H-1 NMR and UV-Vis spectroscopy. Self-association constant of 1a to 2a in CHCl3 (including 0.5% ethanol) was determined as 1.84 x 10(7) M-1 by UV-Vis titration of 2a with N-methylimidazole. UV-Vis absorption and fluorescence spectra of la, 2a, monomer 5M, and its polymer 5P were compared. (c) 2006 Elsevier B.V. All rights reserved.
